Intel lost its appeal against a €1.06 billion (US$1.44 billion) antitrust fine on Thursday when the General Court of the European Union upheld a 2009 ruling by the European Commission that the company had abused its dominant market position.

The Commission had found that Intel had abused its dominant position by offering rebates to customers on the condition they buy all their x86 CPUs from the company.

The General Court dismissed in its entirety Intel's appeal and ordered the chip giant to implement conditions imposed by the Commission in its original ruling to rectify the market situation.

According to the Commission, with 70 percent or more of the worldwide market, Intel was an "unavoidable supplier" of CPUs, an essential component of any computer.

Prior to 2000 there were several manufacturers of x86 CPUs. However between 2002 and 2007 when the market abuse took place, Advanced Micro Devices (AMD) was the only serious competitor.
